ATmega128L

[Josh] got rid of the standard, factory gauges on his GSXR Super-bike and installed a custom built instrument panel which displays some additional parameters which the regular instrumentation cluster did not. He was working on converting his bike in to a Streetfighter – a stripped down, aggressive, mean machine. The staid looking gauges had to go, besides several other mods to give his bike the right look.

Luckily, he had the right skills and tools available to make sure this DIY hack lives up to the Streetfighter cred of his bike. The important parameter for him was to log the Air / Fuel mixture ratio so he could work on the carburation. Along the way, he seems to have gone a bit overboard with this build, but the end result is quite nice. The build centers around a Planar 160×80 EL graphic display lying in his parts bin. The display didn’t have a controller, so he used the Epson S1D13700 graphic controller to interface it with the microcontroller. An Atmel ATmega128L runs the system, and [Josh] wrote all of his code in “C”.
